AVERAGING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 257,430, dated May 2,1882.

Application filed February 16,1882.

To all tchom it may concern Be it known that I, WILLIAM S. AUOHIN-oLoss, a citizen of the United States, residing at Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, have invented new anduseful Improvements in Averaging-Machines, of which the following is aspecification. This invention relates to an improvement on that class ofmachines which I have described in Letters Patent No. 235,723, datedDecember 21, 1880, said improvement consist ing principally in thecombination of the platform with the pivots or knife-edge bearings onwhich said platform oscillates, and with mechanism for changing in ahorizontal direction the relative position of the platform and itsb'earings,said platform being provided-with a series of suitable groovesor receptacles to receive representative weights, and corresponding tomarkson a scale, as will more fully ap pear hereinafter. With theplatform are combinedcounterweights, which when the platform is moved inone direction move out in the opposite direction, so as to preserve theequilibrium of said platform on its bearing-sin any position into whichsaid platform may be moved.

My invention further relates to some details in the construction of themachine, as fully explained in the following specification.

In the accompanying drawings, Figure 1 represents a plan or top view ofmy machine. Fig. 2 is an inverted plan of the same. Fig. 3 is atransverse vertical section of the same. Fig. l is a face view of one ofthe plates which carry the knife-edge hearings on a largerscale thanthe-previous figures. Fig. 5 is a partial longitudinal section on alarger scale than Figs. 1, 2, and 3.

Similar letters indicate corresponding parts.

In these drawings, the letter A designates the platform, which in theexample shown is provided with tubular side bars, B B, and which restsin the saddle O, the edges of which arecurved up to fit the side bars, BB,(see Fig. 3,) so that the platform can be moved in the direction ofitslength on said saddle, or if the platform is held stationary the saddlecan be moved in the direction of the length of said platform. I Y

On each end of the saddle O is secured a plate, D, (best seen in Fig.4,) and from these (No model.)

plates extend the knife-edge bearings c a, Figs. 2 and 3, the seats ofwhich are in standards b I), rising from the base E. The plates D aresecured to the saddle U by screws 0 c, passing through slots, so thatsaid plates, together with the knife -edge bearings, can be adjusted upand down and the knife-edge bearings can be brought in the properrelation in regard tothecenterofgravityof theplatform A. Into thetubular sidebars, B B, of the platform A are fitted cylindrical bars FF, which form the counter-weights, which will be hereinafter more fullyexplained. From the under sides of these counter-weights project pins ffff*, (best seen in Fig. 2,) which extend through slots 0 in the tubularside bars, B B.

On the bottom plate of the saddle O are secured four pulleys, d d. d andfrom the pinsff j"f* extend chains 1 9* g 9" round the pulleys d (l (1(W respectively, to eyebolts h h* It'll/ which are secured in the endpieces, if, of the platform, and which serve to keep the chains taut. Ifthe platform is drawn out in the direction of arrow 1, thecounter-weights F F are moved in the opposite direction by the action ofthe chains 9* g and if the platform is drawn out in the direction ofarrow 2 the counter-weights F F are moved in the opposite direction bythe action of the chains 1* g*, the motion imparted to thecounterweights being always twice that imparted to the platform. Theweight of the counter weights, together with the chains, is so adjustedthat the equilibrium of the platform is preserved when it is drawn outin one direction as well as when it is drawn out in the oppositedirection or brought in its central position, provided the paper scale Gis placed upon the platform. This paper scale consists of a piece ofpasteboard about one inch wide an d iust long enough to drop between theend bars of the platform, and its weight must be taken into account,because when the platform is drawn out the paper scale moves with itor,in other words, because this paper scale, when placed upon the platform,forms in fact an integral part of said platform. Of course this scalemay be made of sheet metal or any other material.

The platform is provided"ith a series of transverse grooves, j, whichare at equal dis- On the 4th of the month for $530 On the 8th 500 On the15th 1,000 On the 16th 200 On I the 19th 150 On the 21st 150 Place oneweight representing 500 and three weights representing 10 each intogroove No. 4 of the platform A one weight representing 500 into grooveNo. 8; one weight representing 1,000 into groove No. 15; one weightrepresenting 200 into groove No. 16; one weight representing 100 and onerepresenting 50 into groove No. 10; one weight representing 100 and onerepresenting 50 into groove No. 21, the number of each groove beingindicated by the inner row of figures on the paper scale. Then draw outthe platform in thedireclion of arrow 1 until the equilibrium isrestored, and the Figure 12 opposite to theindices It gives the averagedate of purchase-that is to say, the man who boughtthe above lots, say,on thirty days, would have to pay $2,530 on the 12th of the followingmonth.

If payments are to be calculated for sixtyor for ninety days,the averagedate of purchaseis found in the same way, and the paper scales canreadily be marked off to correspond to different problems. In fact, Ipropose to add to each of my machines a number of differentscalessuch,forinstance, as for one month, for two months,t'orfourmonths, for eight months, also for fifteen days, for thirty-onedays, for sixty-two days, for one hundred and twentyfour days, and soon, as may be required by the purchaser and by the nature of the problemto be solved by my machine. U From the foregoing description it will beseen that by means of my machine I am enabled to determine the center ofgravity of any combination of representative weights by retaining saidweights in suitable grooves or guides on a platform perfectly balancedon suitable bearings, and then moving said platform or its bearings,orboth,horizontally until the combination of weights is in equi poiseabout the common hearings or fulcrum, and thereby their point of commoneffect or their average location is ascertained.

It will be noticed from this description that in the apparatus abovedescribed the representative weights have no counter-balance whatever,and the platform alone has a counter-balance, while in the apparatusdescribed in my Patent, No. 235,723, the representative weights and theplatform have separate and distinct counter-balances.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, substantially as hereinbeforc described, oftheplatform provided with a series of suitable grooves or receptacles toreceive the representative weights, and corresponding to the marks on ascale, the pivots or knife-edge bearings on which said platformoscillates, and mechanism for changing in a horizontal direction theposition of said platform in relation to its bearings.

2. The combination, substantially as hereinbefore described, of theplatform provided with a series of suitable grooves or receptacles toreceive the representative weights, and corresponding to the marks on ascale, the pivots or knife-edge bearings on which said platformoscillates, mechanism for changing in a horizontal direction theposition of said plat form in relation to its bearings, and thecountor-weight.

3. The combination, substantially as hereinbefore described, of theplatform provided with a series of,suitable grooves or receptacles toreceive the representative weights, and corresponding to the marks on ascale, the saddle which supports said platform and allows of moving thesame in the direction of its length, and the knifeedge bearingsextending from the saddle.

4. The combination,substantially as hereinbet'ore described, of theplatform provided with a series of suitable grooves or receptacles toreceive the representative weights, and corresponding to the marks on ascale, the saddle which supports said platform and allows of moving thesame in the direction of itslength, the knife-edge bearings extendingfrom the saddle, and a counter-weightconnected to the platform so as tomove in a direction opposite to that in which the platform is moved.

5. The combination, substantially as hereinbefore described, of theplatform, the saddle which supports the platform and allows of movingthe same in the direction of its length, the knife-edge bearingsextending from the saddle, the counter-weights connected to theplatform, the pulleys secured on the saddle, and the chains or cordsextending from the counter-weights round the pulleys to the platform.

6. The combination, substantially as hereinbefore described, of theplatform, the saddle which supports said platform and allows of movingthe same in the direction of its length, the knife-edge bearingsextending from the saddle, the tubular side bars of the platform, thecounter-weights fitted into said side bars, and mechanism for connectingthe counterweights and the platform so as to cause them, when moved, tomove in opposite directions.

IIO

7. The method, substantially as hereinbefore described, of determiningthe point of common efi'ect or the average location of a number ofrepresentative weight-s by distributing said weights on a balancedplatform and then changing in a horizontal direction the position ofsaid platform in relation to its bearings without disturbing theequilibrium of the platform until the representative Weights are inequilibrium in regard to the bearings of the 10 platform.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscrihin g witnesses.
